Hi All,
I'm a fresh man in cognos.
I have a main query for the cross table includes 3 types of data.
Now I want to create 3 charts of each type of data.
So I create 3 sub query base on the main query and filter them with such as 'dataType=A', 'dataType=B'
Then I run the report. It comes the error:
Initially, in data source type(s) '', the function 'source' is not supported in 'TabularOperationProvider'. After decomposition, in data source type(s) '', the function 'source' is not supported in 'TabularFuncProvider'.
Can anyone help me?
